Toy

Abstract

This toy is a ball-rolling toy. It has multiple long boards arranged vertically, and each long board has a horizontally extending slot. The slots gradually widen from one end to the other, so a ball placed on a slot rolls from one end to the other. When a ball rolling over a slot reaches a point where the slot's width is larger than the ball's diameter, it passes through the slot and falls onto a slot in a board on the lower level. The slots on the lower level widen in the opposite direction to the slots on the upper level, so a ball that falls onto a slot on the lower level rolls in the opposite direction to the slot on the upper level.
